How to Build my 8 Mining Rig For Ethereum?

With all this crypto hype, it is normal that you may feel tempted to build your 1st mining rig, and flavor the profits of your work.In this article we will try to guide you through all the process, please note that prices were based on Amazon US prices, you may find the same equipment at different prices depending from where you are.

All the installation was thought to be upgraded in the future, as the Motherboard olds 16 GPUs and to be over-dimensioned in power availability.

The materials you will need for your rig:

  • A mining rig frame that can hold all your hardware in

In tis case you must consider all the GPUs, with possible expansion that you may like to acquire later.

Price to expect for a 8 GPU unit around 180USD

  • 1xMotherboard

There are several models on the market with capabilities to run 8,  GPUS, for our example we chose the

Asus Z270-P

The Prime Z270-A is one of Asus’ best motherboards in the mid-range, and its specification is extremely well-balanced

The basic specifications are covered. The Prime supports 64GB of DDR4 at speeds of up to 3866MHz, and the two PCI-Express x16 slots can run in dual 8x mode – so there’s enough bandwidth to run two high-end GPUs for future expansion.

Price  170 USD

Power consumption: 65 W


  • 1xCPU:

G3900 Skylake Celeron, used

In this matter as the mining capability for ethereum lyes on the GPUS, we decided to use a USED dual core for the job.


Price: 50$

Power consumption : 51 W

  • Ram: 4GB DDR4

For the ram we will use Kingston HyperX Fury 4GB 2133MHz DDR4

Kingston is well known for it’s computer components, and for good reason, because they are good!

The cheapest option in their HyperX FURY line is this 4GB single DIMM option.

Price 70 USD


  • GPU: 8X Radeon RX580 8Gb

Radeon, Shapphire, Gigabyte, Asus, MSI, Powercolor are some of the Manufacturers using AMD RX 580 Chip


Memory Speed (Effective) 8 Gbps
Max Memory Size 8 GB
Memory Type (GPU) GDDR5
Memory Interface 256-bit
Max. Memory Bandwidth 256 GB/s

Mining Hash Rate per overclocked unit – 32 Mh/s x 8 = 256 Mh/s

Power consumption – 185 W x 8 = 1480 W

Price – 600 USD x 8 = 4800 USD

  • PSU: 2X Corsair AXi Series, AX860i, 860 Watt (860W) ( Total 1720 W) + CablesThe latest

80 PLUS Platinum certified, delivering over 92% energy efficiency at real world load conditions. Active Power Factor Correction (PFC) with PF value of 0.99. Universal AC input from 90~264V

Price 230 USD x2 = 460 USD

  • Risers: 8X Sata Ver007 + 1X Molex Ver006


4-Pin riser kits are the perfect solution for setting up Ethereum mining rigs (or any other GPU-mined altcoin), whether small open air rigs or large rack based miners.

How much can i profit from this mining rig?

With a total 256 Mh/s and a operating consumption of 1400 W and a KWh of 0.18USD and the Ethereum value in 1-19-2018

Printed in 1-19-2018

With a Profit Ratio per day  of 343% and  a profit per month of $624 we can not deny it is profitable, and if you do the math you will discover that you return your investment in less than 10 months.

Get your hands on the job and start building that mining rig you so much desire.
